The IC component 25AA256/S16K is a 256 Kbit serial EEPROM memory chip manufactured by Microchip Technology. This integrated circuit offers non-volatile data storage and is typically used to store small amounts of critical data, such as configuration data, program code, or system parameters.
Key Features:
1. Memory Capacity: The 25AA256/S16K has a memory capacity of 256 Kbits or 32 Kbytes, making it suitable for storing a moderate amount of data.
2. Serial Interface: This IC uses a simple, three-wire SPI (Serial Peripheral Interface) for communication, allowing easy integration into most microcontroller systems.
3. Non-Volatile Storage: The data stored in the 25AA256/S16K is non-volatile, meaning it retains its information even when the power is turned off.
4. High-Speed Read and Write: The chip provides fast data access, with a high-speed clock frequency of up to 10 MHz for read and write operations.
5. Multiple Addressing Modes: The component supports three addressing modes, namely Byte Mode, Sequential Mode, and Page Mode, providing flexibility in accessing data stored in the memory.
6. Write Protection: The 25AA256/S16K includes a hardware write-protect feature to prevent accidental modifications or unauthorized access to stored data
